WIRE-CUTTING MACHINE.

Application filed December 2, 1920. Serial No. 427,679.

To all whom. it may concern Be it known that I, ALEXANDER S. Srnnn, a citizen of the United. States, residing at Buffalo, in the county of Erie, State of New York, have invented. certain new and useful Improvements in lVire-Cutting Machines; and I do hereby declare the following to-be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improvement in Wire cuttinomachines, and the invention has for its ObJQCt to provide mechanism for permitting a number of pieces of wire of uniform length, such as are used, for instance, in baling shingles of composition roofing material, to be simultaneously cut, wherein a drum is provided upon which the wire to f be cut is laid in coils, one alongside each other, the drum having a longitudinally extending passage on its peripheral surface along which a cutter may be passed to sever the lengths of wire.

A further object is to provide a winding drum for the wire which may be varied in diameter, to provide for the cutting of the wire into different lengths.

In the drawings Figure 1 is a side viewof the improved machine,

Figure 2 is an end view,

Figure 3 is a section on the Figure 1,

Figure f is a section on the line l& of Figure 5, and

Figure 5 is a section on the Figure 4:. v I

In baling shingles of composition roofing material and the like, lengths of wire are used, either flat or circular in cross-section, which in the ordinary practice, are cut from a reel, the lengths of wire being withdrawn from the reel and cut off in succession. This is a slow and tedious process, requiring the continuous service of an operator. In the present invention a series of lengths are cutat the same time, the pieces of wire being of uniform length.

In the present embodiment of the invention a suitable supporting frame 1 isprovided upon which is arranged a pair of open bearings 52 for receiving a Wire supporting reel 3. A drum is also mounted on the me e aid eras; assist n f hea line 33 of line 55 of 4 which are secured in spaced relation on a shaft 5, and the shaft is jonrnaled in bearings 6 on the frame. The wire is supported by a series of bars 7 which are arranged between the heads,'and these bars are arranged to be moved toward and from the shaft 5 to vary the diameter'of the drum, in order to vary the length of the pieces of wire which are cut.

The heads 4 have inwardly extending pairs of lugs] 8, the said lugs of eachpair To the inner end of each screw inside the innermost h1g8, there is secured abcvelgear wheel 10, and the gears at each head 4f are engaged by a bevel gear wheel 11 cured on a'sleeve 12 which is jonrnal'ed on the shaft 5 between the heads. The-sleeve is turned by means of a hand wheel arranged between the heads, the said wheel consisting of a hub portion 13having radial pins 14: for conveniencein manipulating the same, and the hub is secured to the sleeve. It'will be obvious that by turningthe hand wheel in-the proper direction, all of the bars 7 may be simultaneously moved toward or from theshaft. 5, to vary the diameter of the drum.

Each head 4 has a slot 15, which extends inwardly from the edge thereof, and the slots of the two heads are in register. The slots 15 are for permitting the t re of a cutter by means of which the coils of wire on the drum may be cut, the slots being of suliicient depth topermit the cutter to pass beneath the coils, that is between the coils and the shaft. Referring to Figure 4; .itwill be seen that the slots extend to the innermost lug 8, so that the bars 7 will never be ad justed inwardlybeyond the inner ends of the slots.

coils of wire which are wound on the A pulley 16 is secured to the shaft 5 of the I drum, and this pulley is, engaged by a belt lid threaded engagement with the screw. pair of rollers 25 extend upwardly from the ley 18 on a shaft 19 which is journaled on the frame, parallel with the shaft 5, in bearings 20. The shaft 19 is connected with any.

suitable source of power, as. for instance a motor which may be seated on the frame. The bearings 2 are open bearings, andreferring to Figure 1 it will be noted that .they face away from the drum, so that there is no tendency of the wire supporting reel to spring out of the bearings when the wire is withdrawn therefrom.

Mechanism is provided for laying the coils carriage, the said rollers being connected at their upper ends by a cross-plate 26,, and the wire indicated at 2'? passes between these rollers.

The pulleys 23 and 23 are as before stated loose on the screw, and they are adapted to be connected to the screw by clutch mechanisms indicated at 28. Each of these clutch mechanisms is controlled by a lever 29, which has a fork at one end for engaging an annular groove in the movable member of the. clutch, and each lever is pivoted in- ,tenmediate its ends to anfiarmBO extending outwardly from-the adjacent bracket 21. The lower ends of the lovers are connected .by a bar 31 which is ,mounted to slide laterally of the frame 1, and. the said bar has stop collars 32 arranged thereon, in position to be engaged by the carriage 2d at the end of itsmovement in each direction. it will be evident that when theicarriage engages a i stop collar, .it will move the bar longitudinally, and transversely of the frame, and 71116011116013 one clutch 28 and release the other. Thus, the pulleys 23 and 23 will be connected in alternation to the screw, to cause the same to rotate 2111 opposite directions, and the movement of the screw will be controlled by the movement of the carriage. Belts and 38 connect 'the pulleys 23 and 23 with pulleys S t on the .drum shaft :the sleeve between the 5. The belt 33 is crossed, so that the pulley 23 will drive the screw in the opposite direction to that in which it will be driven by the pulley 23. y

The operation of the machine is as follows With a reel of wire in the bearings 2, and

with the free end of the wire connected to. the drum 11113113 suitable manner, as for re stance wrapping it about a bar 7, when the drum is started to rotating, the wire will be withdrawn from the reel, and will be laid in coils onsthe drum. After the wire has beenlaid, the drumis checked, and the cutter is passed beneath the coils of wire, moving in the slots 15. Each coil of wire -.will be out, and the lengths of wire into which the coils are cut will be uniform. or approximately so. If several layers of coils are wound on the drum, it will be evident :that

the lengths will vary slightly, .the outermost coils being a trifle longer than the iinieumost coils. In order to vary the lengths cut, the bars .7 may be :moved inwardly or outwardly by rotating the sleeve 12. lVhen this sleeve is turned in one direction, theabars will .be moved inwardly, and :the coils laid upon the drum will be of less-diameter than when the bars are moved outwardly. Any preferred fornrof cutter maybe used -.to sever thecoils. hat T claim is': I 1. In a machine for winding and cutting strandsof wire and the like,.-a winding drum of variable diameter, guide meanscontrolled by the rotation ofsaid drum for feeding the wire to said drum an successive layers,-,and

manual means between the heads of said drum including a hand wheel therenr and screw mechanism ope "able thereby for varying'thediameter thereof, whereby to provide for cutting wires of the desired length.

2. In a machine for winding and cutting strands of wire and thelike, a winding drum of variable diameter, guide meanscontrolled by the rotation of-said drum for feeding the wireto said drum in successive layers, and

manual means for varying :the diameter of the drun'iincluding a sleeve rotatably mount ed on thedruln shaft, radial screws ad acent the ends of the drum geared to said sleeve for simultaneous operation and a handle on drum heads for actuating saidscrews.
